To all whom it may concern.'

Beit known that we, Axnnnw J. Herren and HENRY PRINDLE, citizens of the United States, residing at Oakland, in the county7 of Alameda and State of California, have invented new and useful Improvements in F ume-Condensers, of which the following is a speeitication.

hls invention relates to eenden-sers, and

more particularly to fume condensers.

he object of our invention is to provide a, novel, and eii'ective apparatus for eliminating, extracting and abating-poisonous fumes of sulfurous dioxid, and condensing or suppressing the deleterious gases arising rom smelters, or roast furnaces, acid works, factories and garbage plants.

t is also an object ot' our invention to provide means in combination which are adapted to receive, cool and condense the poisonous fumes and to abstract therefrom ing from the condensation. l

The invention'consists of the parts and the construction andcomhination ot parts hereinafter more fully described and claimed, having reference to the accompanywhich` lgurc l is a side view of the device in partial section Fig. 2 is an end view of the ume condenser iu section.

The illustration represents one form of our apparatus which has been embodied in practice; and comprises a suitable frame A, the lou-'erportion ot' which 'toi-insa fluid holding tank 2, and the upper portion of the tank being entirely closed by a housing l of suitable shape and material topropcrly house a horizontally mounted partially subgatherer 3,-which latter is supported upon a horizontal shat't 4l, journaled at 5 upon the frame A. 'lhe receiving end of the housing B is provided at. one end with an upright projecting section (l to which may be vconnected the discharge stack of thc furnace or garbage plant, in conjunction with which tis apparatus is to be used.

he principal lmeclnlnical feature consists of the drum 3, carrying on the inside a spiral or worm construction or flue in the shape of a large conch shell tapered from one end to the other, and having a large mouth and capacity, revolving inthe tank or receptacle 2, which latter is filled with chemical or bath, preferably of calcium hyand lthe uncondensed drate. The fumes are drawn in by vacuum into the housing' B from the stack at every revolution of the receiver of conch shell which takes in a large. mouthful of fumes; the mouth 8 as the drum turns being submerged in the bath, and allowing or forcing the liquid to How through the spiral liuc and forcing ahead of it like a water piston, the trapped gases and fumes. The gases are completely, washed of the deleterious` matters and are delivered to the condenser which has a compartment for eliminating the arsenical compounds and base metals as later described.

.A collecting and discharging screw 2S is tank,

uring the rotation of the drum l the mouth and chamber ywith which it is connected become charged when at its upper position with a -mass of fumes, and as the mouth 8 revolves into the water at its level 9 the fumes are thereby prevented 't'rom escaping, and gradually chamber where it is scaled by the upper .level of the water.

The contracted discharge vend l() of the fume receiver-3 bears in and communicates with a fixed elbow 11,' which discharges downwardly at 12, and below the level of the solution in the tank 2; thus it will be seen that it a large volume of fumes or other fiuidbe caught by the revolving drum il and gradually carried below the water level i), it is gradually compressed and cooled by reason ot its engagement with the liquid in thetank', and eventually escapes through the dmvuwardly opening elbow 12 into that end oi the tank.

Preferably a partition 14 divides the main body of the tank from that portion in which the elbow 12 'is mounted, so that the rising bubbles ot' uncondensed gas and fumes will be directed up to the outlet 15. The torce ot' the compressed air discharging from the elbow into the condensing liquid in the tahk causes a constant ebullition of the liquid, portion ot the it'uxues arises, as indicated by the arrow' o, and pass upwardlyv through a flue 15 by which they are directed downwardly througl'i a washing chamber 16.

The fume or vapor inlet 6 ofthe tank is suitably divided oil from the vapor outlet l5, sothat the fumes must travel through the compressed in a
